The question is a bit hard to give a definite answer to, because there are so many different techniques and scales used to measure "strength" and "full hardness" for steel. One - an it is only one of several - scales used for measuring hardness of steel is the Rockwell scale, where Rockwell C-60 would be very hard, indeed. Strength - again, what kind of strength do you mean? Torsion strength? Compression strength? Shock strength? Abrasion strength? All of those - and many more - have specific alloys and hardening procedures for optimum results. That's about as specific as I can get, given the broad generality of your question.
it becomes strength
to insure the steel is fully hardened
to insure the steel is fully hardened
the strengths are that is can be hardened and tempered but the weaknesses is that is isnt easy to bend hope this helped :)
Hardened steel can rust if it is not properly protected, as it is still susceptible to corrosion due to its iron content. The hardness treatment improves its strength and wear resistance but does not make it immune to rust. To prevent rusting, it is essential to apply protective coatings, such as oil or paint, and to keep the steel dry and clean. Regular maintenance can help extend the life of hardened steel items in humid or corrosive environments.
440C Steel can be hardened upto 58RC unlike D2 (SKD11) which is upto RC 60 Hardness.
The best cutting disc for hardened steel is a diamond cutting disc. Diamond discs are known for their durability and ability to cut through tough materials like hardened steel with precision and efficiency.
The two types of steel that appear to have their properties combined in tempered steel are hardened steel and ductile or malleable steel. Tempering involves heating hardened steel to a specific temperature and then quickly cooling it, allowing the steel to maintain some of its hardness while also gaining increased toughness and ductility.
There isn't really a difference since a piece of steel can both stainless and air hardened. Stainless steel is a steel alloy with a minimum of 10% chromium content by mass. Metals can be hardened in a variety of ways. They may be work hardened, tempered, air or oil hardened, for example. Tempering, or the systematic heating, cooling and reheating of a material is one technique that might be used to harden steel.
Hardened steel can rust faster than regular steel because the hardening process can disrupt the steel's natural corrosion resistance. This can lead to increased vulnerability to rust and other forms of deterioration. Hardened steel may also have more exposed surface area due to the hardening process, which can make it more prone to rusting.
Not hardened steel
yes
